Metallics JG5HTB106 – Frequently Asked Questions
1) Is the Metallics JG5HTB106 hex tap bolt threaded all the way to the head?
Yes. A hex tap bolt is fully threaded rather than having a plain shank, so the full 5 inch length of the JG5HTB106 carries thread at 16 threads per inch, right hand. That matters when you are pulling a motor base down into a tapped hole or a through-hole with a nut at any grip length, since you are not limited by where a shank ends.
2) How strong is a grade 5 hex tap bolt, and will it hold a motor mount?
Grade 5 means medium carbon steel, heat treated, with a minimum tensile and yield rating of 105,000 psi and a hardness of Rockwell C19-30. Metallics lists this exact bolt for mounting motors to machinery, and it is common in automotive and truck repair work. If your drawing calls for grade 8 or a stainless fastener, this is not a substitute.
3) What hole size do I need to drill for this 3/8 bolt?
Outside thread diameter runs 0.3690 to 0.3750 inch, so a 3/8 inch clearance hole is tight. For a through-hole, drill 13/32 inch or 7/16 inch depending on how much slop you want for alignment. For a tapped hole, the thread is 16 per inch, right hand.
4) Does this Metallics hex bolt meet ASME dimensional standards for a government or institutional spec?
Threads and head dimensions follow ASME B18.2.1-2012, and the steel is to AISI 1008-1026. On procurement flags, Metallics lists the JG5HTB106 as both ARRA compliant and Buy American compliant. Country of origin is China, which matters if your contract requires domestic melt and manufacture rather than the Buy American cost-of-components test.
5) What wrench or socket size fits the head on this 3/8 grade 5 hex bolt?
The hex head measures 0.551 to 0.562 inch across the flats, which is a 9/16 inch wrench or socket. Head height is 15/64 inch, with 0.16 inch of wrenching height, so a standard open-end or a six-point socket both get full purchase.
6) How many bolts come in the Metallics JG5HTB106 jar, and can I buy fewer?
It ships as a jar of 50, and 50 count is the order minimum, so the jar is the smallest buy. Total packed weight is 3211 g. Metallics also makes other sizes and quantities in the G5HTB and JG5HTB hex tap bolt series available by request.
7) What is the difference between a hex tap bolt and a hex cap screw for mounting equipment?
Both use the same six-sided head and the same wrench, but a hex cap screw has an unthreaded shank under the head while a tap bolt is threaded its whole length. The JG5HTB106 is the tap bolt version in 3/8 by 5 inches, grade 5. Pick the tap bolt when you are threading into a tapped boss or when the grip varies; pick a shouldered cap screw when you want the plain shank bearing in the hole for shear alignment.
